I think there is one black hole in my mind. Chasing after the advertisement and buy many things I do not need.It is bad to know about many things. Ten years ago I only wish I can get a computer. I never know what is the Alienware. Now I get one Alienware Aurora on the desk. I never know a computer can be so fast. 3 years ago, I never think a denim pants can sell at around 200 dollars per pair. Now I have owned three pairs of G-Star. Two years ago, I never know I can order the junk food from online. Now I am over weight because of the junk food. People all are trying to reach a higher grade for their life quality. They enjoy trying the good things. But soon that form one kind of their habbit. Men's greedy heart is one black hole we can never fill. So am I. 

Money is easy to be wasted. Normal people woud not spend thousands on the toys as a adults. But when I am looking at those boxes in the corner I feel a little regret for what I have done. It is one kind strong desire to own something. This thing twisted our mind and make us have to press the buy now button. I believe the shopping have already turned to a mental disease for a number of people among us. I am one of these people. We can not control and keep trying to bring ourselves those things do not have any use for our lives. 

Control is a basic talent of adults. When we are kids we can't stop eating the sweets, that make our teeth broken. But after several years, we should learn to control ourselves. We have the income every week. But we should keep it for the life in future. You can not just divide it into 7 pieces. If one day you need the money, you would feel regret for what you have done. 

To fill this black hole, we must learn to control. The mind control would help you shut down the black hole. Life is a challenge.
